Summary

What Researchers Did

Researchers investigated in rats whether a protein called BDNF contributes to increased seizure sensitivity after exposure to high-pressure oxygen (100% O2 at 5 atm).

What They Found

The study demonstrated a rapid increase in BDNF mRNA within 2 hours after seizures and a temporary rise in BDNF protein 1 day after seizures induced by hyperbaric oxygen. Administering exogenous BDNF (12 microg) significantly shortened the latent time to seizures in subsequent HBO exposures.

Canadian Relevance

No direct Canadian connection identified.

Study Limitations

This study was conducted on rats to understand oxygen toxicity and its findings may not directly apply to humans or to the lower pressures used in therapeutic hyperbaric oxygen treatments.
